Pulmonary edema that isn't caused by increased pressures in your heart is called noncardiogenic pulmonary edema. In this condition, fluid may leak from the capillaries in your lungs' air sacs because the capillaries themselves become more permeable or leaky, even without the buildup of back pressure from your heart.
So in other words, ambulatory medical care is a term for almost all of the medical appointments and treatments people receive regularly.
Ambulatory surgery centers are free-standing facilities with operating rooms, but they are not hospitals. These centers perform procedures that allow the patient to recover at home once anesthesia has worn off and the patient is able to care for themselves with minimal assistance.
